要約(英語): High-performance power switching devices are used to realize high-performance power converters. These devices tend to generate high-speed switching harmonics that cause electromagnetic interference (EMI). There are several methods for reducing undesirable effects of EMI. An EMI filter or shielding is one of the most popular ways to reduce EMI; however, both EMI filter and shielding increase the cost, size, and weight of power modules. It is well known that the shape of the switching transient strongly affects the harmonics distribution. This paper proposes a new method for reducing high-frequency noise at specific frequency bands by modifying switching transient slopes. This paper describes the improvement in the method of transient wave calculation for obtaining more effective waveforms. In addition, it provides experimental verifications to show the feasibility of the proposed method.
